Application filed November 14 1905. Serial No. 287,233.

T0 at whom, it may concern.-

Be it known that I, CHARLES FEIsTER, a citizen of the United States,residing in Ardsley, Westchester county, New York, have invented certainnew and useful Improvements in Ice-Creepers, of which the following is aspecification.

My invention relates to improvements in what are termedice-creepers-that is to say, attachments for shoes to prevent the wearerfrom slipping on snow and ice and to give a firm foothold.

My invention consists in the novel construction of the device.

The objects of my invention are to im prove and simplifyice-creepers'such as described, to make the same simple, reliable,inconspicuous when in place, and easily operated to throw the teeth orblade into or out of operative position, and to make such device cheapto manufacture and easy to apply.

I will now proceed to describe my invention with reference to theaccompanying drawings, illustrating one embodiment thereof, and willthen point out the novel feature in the claims.

In the said drawings, Figure 1 shows a side view of a shoe with myimproved ice-creeper applied thereto. Fig. 2 shows a bottom view of aportion of the shoe with the creeper in lace thereon. Figs. 3 and 4 aresimilar ongitudinal sections of the creeper in place, Fig. 3 showing theblade withdrawn out of operative position, and Fig. 4 showing the bladein operative position.

My improved ice-creeper comprises a baseplate 1, designed to be securedto the sole of the shoe and to the heel thereof by suitable means, suchas nails 2, and to be located directly in front of and secured to thefront side of the heel. the base-plate is bent substantially at rightangles to the main portion thereof, and preferably ears 3 are likewiseformed on said base-plate and bent downwardly to form bearings for thecam 4. To this base-plate is secured a spring-blade 5, guided and bracedlaterally by the ears 3. The cam 4 is provided with a projecting lug 7,which when horizontal permits the teeth 6 to clear the ground, whilewhen said cam is turned so as .place on a stem 10 by a rivet 11.

For this purpose the end of to bring the lug downward the teeth 6 arepressed down so as to bite into the snow or ice.

For convenience in turning the cam an 5 5 operating finger-piece 8 isprovided. Said finger-piece is turned at right angles to the cam, so asto lie closely against the heel or against the sole of the shoe,according to its position. The blade 5 is preferably attached 6oremovably to the base-plate 1, and I have indicated for the purpose ahead 9, held in When the footing is not slippery, the teeth 6 willordinarily be in their upper position clear of the ground, and thereforeentirely out of the way. When snow or ice is encountered, thefingerpiece 8 is turned, therefore forcing theteeth 6 downward andbringing the device into use. Because of the location of the creeperjust in front of the heel it is very inconspicuous and will scarcely benoticed. The device is easily applied to and removed from the shoe.

What I claim is- 1. In an ice-creeper the combination with a base-platehaving bearings, of a springblade secured thereto and toothed at oneend, and a rotary cam mounted in said bearings in said plate andarranged to actuate said blade.

2. In an ice-creeper the combination with a base-plate having bearings,of a springblade secured thereto at one end, the other end of said bladebeing turned at an angle and toothed, and a rotary cam mounted in 85said bearings in said plate and arranged to actuate said blade.

3. In an ice-creeper the combination with a base-plate adapted to besecured to the under side of the shoe-sole in front of the heel 0 andhaving a right-angled portion arranged to rest against the heel anddownwardlyturned ears infront of such right-angled portion and havingbearings, of a spring-blade secured at one end to said base-plate and 5having a toothed portion working between said ears, and a rotary cammounted in the bearings in said ears and arranged to actuate said blade.

4. In an ice-creeper the combination with IOO a base-plate havingbearings of a springbladesecured theretoland toothed at one end and arotary cam mounted in the bearings in In testimony whereof I hereuntoaflix my said plate and having an operating fingersignature in thepresence of two witnesses. piece projecting beyond the plate and turnedat substantially right angles to the main por- CHARLES FEISTER' tion ofthe cam, whereby such operating Witnesses: portion lies closely againstthe shoe in all po- MAY I.
